Abstract
An engine operation control apparatus includes a controller configured to: decide an engine operation time point based on a lookup table in which a learning value that is previously learned is stored when a request to switch to an HEV mode occurs; determine whether to engage an engine clutch by comparing an engine RPM when a speed of an engine is synchronized with a speed of a motor with a first motor RPM; operate the engine at the engine operation time point and control engagement of the engine clutch depending on the determination; and store the engine operation time point based on a second motor RPM at a synchronization completion time point when a learning condition of the engine operation time point is satisfied when the speed of the engine and the motor are synchronized.
